[Autonomic Nervous System] Why Your Heart Races and You Can’t Fall Asleep When You Lie Down to Sleep

  • Key points
  • Ulsan During consultations for autonomic nervous system dysfunction, it is common for patients to report, “When I lie down to sleep, my heart races and I can’t fall asleep.”
  • There are people who manage to get through the day somehow, but when they lie down at night, their heart races, they feel short of breath, or their mind becomes too clear, making it difficult to fall asleep.
  • In such cases, people tend to worry, “Could there be a problem with my heart?” but when they’re told that the test results show no specific abnormalities, they’re left with a different kind of unease.

[Endometrial Adhesions] If Your Menstrual Flow Has Decreased and You’re Having Trouble Getting Pregnant, Here’s What to Check First

  • Endometrial adhesions refer to a condition in which the inner walls of the uterus stick together, which can affect the shape of the uterine cavity or the flow of menstrual blood.
  • If your menstrual flow has noticeably decreased or stopped following a D&C after a miscarriage, uterine surgery, or an intrauterine infection, or if you are experiencing recurrent miscarriages or difficulty conceiving, you should consult an OB/GYN to determine whether an evaluation of the uterine cavity is necessary.
  • It can be concerning if your menstrual flow decreases significantly compared to before after a miscarriage or childbirth, or if you experience lower abdominal pain around your expected period but have almost no bleeding.

[Digestive System] If you feel bloated and have a tight sensation in your upper abdomen after eating, check for functional dyspepsia

  • Ulsan A common scenario in consultations for indigestion involves patients who experience recurring symptoms such as bloating after meals, early satiety, a feeling of tightness in the epigastric region, belching, and nausea, even though endoscopy reveals no significant abnormalities.
  • In such cases, it is necessary to consider the motility and sensitivity of the stomach, as well as autonomic nervous system tension, just as with functional dyspepsia.
  • Some people are told that their test results show no specific abnormalities, yet they experience a feeling of fullness in their stomach after every meal, feel full even after eating only a small amount, and have a tight sensation in their upper abdomen, making daily life uncomfortable.

If you experience recurring palpitations and insomnia, consider the possibility of autonomic imbalance
